Fortran code in Matlab

I have a Fortran code which I need to simulate in Simulink. Before creating a C mex file, I am only compiling the Fortran code in Matlab using Intel Parallel Studio XE 2015. However, I get the following error when I compile it.

SUBG.f(1078): error #5078: Unrecognized token '&' skipped
     *     &           /'    large nromalization factor in fixvol.'
-----------^

And here is the snippet of the code where the error lies.

if (abs(1.0-xnormc).gt.0.05 .or. abs(1.0-xnormr).gt.0.05) then
         write (lutty,1800) xnormc,xnormr
 1800    format (/' *****Warning'\
     &           /'    large nromalization factor in fixvol.'!In this line the problem lies
     &           /'    for coal =',f8.2,'  for rock =',f8.2) 
      endif

Moreover, I searched the internet for the said problem and found out that it mostly occurs when an

unknown character sneaks up in the code while copying-pasting it into Matlab.

Anywork around about this problem!

Thankyou.
